WINDOW VENTILATOR Filed Jan. 29, 1931 /NVE/v To@ Arm/@N5 y Patented Jan. 3, 1933 UNITED STATES WESLEY T. CROUSE, OF'ST. LOUISri-MISSQURI WINDOW VENTILATOR Application led January 29, 1931. 'SerialfNm 512,020.

This invention relates to a certain new and useful improvement in window-ventilators and has for its chier" object the provision of a sectional window-ventilator of simple and inexpensive structure, which may be easily operatively installed, which is conveniently adjustable for use with windows of dierent sizes, and which is efficient in the performance of its intended functions.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawing,-

Figure l is an elevational view of a standard window and its frame equipped with a ventilator embodying my invention;

Figure 2 is an enlarged vertical sectional view through the window, frame, and Ventilator, taken approximately on the line 2 2, Figure l; and

Figure 3 is a transverse sectional view of the ventilator, taken approximately on the line 3 3, Figure 2.

Referring now more in detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, A designates a standard window-frame,

and B designates a standard double-sash window mounted, as is customary, in the frame A.

Suitably fixed latwise upon the inner face of the opposite side-members l and adjacent 1' the sill 2 of the frame A, are plate-sections 3 suitably formed or'provided at or adjacent their outer margins with supports preferably in the form of opposed open-topslide-ways C for the ventilator D, which latter includes a pair of substantially similar separate oblongrectangular sections 4, 4', constructed preferably of glass or other suitable rigid material.

The ventilator-sections 4, 4', are disposed lengthwise in overlapping relation, and adhesively or otherwise permanently fixed to, and extending lengthwise along the respective inner ends of, the sections 4, 4, are strips 5, 5, respectively, each substantially of U-shape in section, as best seen in Figure 3.

engaged with the Icontiguous section 4C- i Formed `preferably integrally -with the' inand at-the oppositeends, of the'strip Vdisposed extensions or Similarly formed integrally withthefinner leg, and at Ythe opposite ends, lof' the strip are oppositely ldisposed Aextensions Yor tongues 7, which are-'likewise bent over and engaged with the contiguous section 4. Thus,

in a simple, ei'hcient manner, the sections 4, 4', are retained in lengthwise overlapping relation, the pairs of opposed bent tongues 6 and 7, at the same time, forming slideways, whereby the sections 4, 4, may be slid--i ably shifted with relation one to the other and the ventilator accordingly conveniently adjusted in length for insertion in the supporting slide-ways C, which, as best seen in Figure 2, are preferably inclined upwardly" and inwardly from the sill 2, so that any air entering through the opening 8 provided on raising the lower sash of the window 3, may be directed inwardly and upwardly into the room or other enclosure by the interposedi ventilator D.

The ventilator is exceedingly simple in structure, may be cheaply and economically constructed, may be readily adjusted in length to meet the requirements of the par' ticular installation, and is exceedingly efcient in the performance of its functions.

It is to be understood thatchanges and modifications in the form, construction, ar-

rangement, and combination of the several parts of the ventilator may be made and substituted for those herein shown and described without departing from the nature and principle ofmy invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is,-

l. A window ventilator comprising a pair of rigid companion oblong rectangular sections disposed in lengthwise overlapping relation, strips U-shaped in section permanently lixed lengthwise upon the respective transverse inner ends of said sections, and extensions on the inner leg of the respective strips bent over in opposed relation upon the opposite outer faces of said sections in the formation of slide-ways engaging the respective sections upon their longitudinal margins for securing the sections together in lengthwise overlapping shiftable relation.

2. A window ventilator comprising a pair of rigid companion oblong rectangular sections disposed in lengthwise overlapping relation, strips U-shaped in section permanently iXed upon and extending throughout the length of the respective transverse inner ends of said sections, and tongues on the inner leg and at the opposite ends of the respective strips bent over and upon the opposite outer faces of said sections in the formation of opposed hooks engaging the respective sections upon their longitudinal margins for both securing said sections together and providing slide-ways for the lengthwise shiftahle adjustment of said sections with relation one to the other.

In testimony whereof7 l have signed my name to this specification.
